鄂尔多斯柠条饲料林适宜收获期的研究

STUDY ON THE APPROPRIATE HARVEST PERIOD OF CARAGANA LAM FEED IN EERDUOSI

根据不同饲料作物的产量及营养成分确定最适收获期,既能保证牧草的生长发育,又能获得高产优质的饲草料。本文从柠条同一植株不同器官、不同生育期以及不同生长年限的营养成分含量几个方面对柠条饲料林的适宜收获期进行了研究。结果表明:柠条饲料林的收获期以2-3年生幼龄林、花期后至落叶前为佳。

Depending on the production of fodder crops and nutrient component to determine the optimum harvest period,we can ensure the growth of grass,but also to obtain high yield and quality of forage material.This article studied the appropriate harvest period of Caragana Lam feed in these aspects of the nutritional content of Caragana in different organs,different growth stages and different growth period.The results showed that： The optimum harvest period of Caragana Lam feed is 2-3 year-old young forests from flowering period to deciduous period.
